Early population ecologists conducted most of their research on small islands rather than on continents because a number of features of island populations make them easier to study. which of the following is not one of those features?
1. lower immigration
2. lower emigration
3. more clearly defined boundaries
4. smaller sizes
5. more stability over time

3. More clearly defined boundaries

Explanation:

Clearly defined boundaries is necessarily not a reason why early population ecology preferred researching on small islands.

Lower immigration and migration, smaller and manageable sample size and more stability over time due to low immigration and emigration activities are reasons why small islands were preferred.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
